SWITCH FOR PNEUMATIC DISPATCH-TUBES.

SPECIFICATION forming part of Letters Patent No. 406,447, dated July 9, 1889.

Application led October 29, 1888. Serial No. 289,376. (No model.)

To all whom t may concern.: cle, the end of the' main tube A bein g slightly Beit known that I, PATRICK KENNEDY, J r., flaring and the opposing end of the switchof Brooklyn, in the county of Kings and State tube fitting therein, and this joint is covered of New York, have invented an Improvement with a rubber sleeve or gasket O, which forms 5 in Pneumatic Switches, of which the followan air-tight joint around the meeting end 0f 55 ing is a specification. the main tube and switch-tube. Surround- Pneumatictubes for message-carriers have ing the main tube A is a collar D, and eX- heretofore been constructed with switches to tending out from said collar are arms D. divert the path of the message-carrier, and Around the switch-tube B is acollar E, and eX- xo said switches have been made as apivoted arm tending out from said collar are arms E, and 6o movable at one end, and the. same has been the ends of the arms E pass within the ends swung into one or another position at the of the arms D and pivot-pins 5, in line with junction of the main tube with the diverging each other, connect the ends of these respecttubes, so as to make a continuous path for ive arms, the center line of said pivots 5 pass- 15 the message-carrier in either one direction or ing through the moving center of the junc- 65 the other. tion of the main tube A and switch-tube B. My invention relates to an improvement in These collars D E and their arms D E and pneumatic switches; and my improved device the pivots connecting the same, serve to hold consists of a movable length of tube, which is the main tube and switch-tube rigidly tozo pivotally secured at one end to the main gether and to provide for the swinging move- 7o pneumatic tube, the other end of the switchment of the switch-tube upon the main tube. tube being movable into position with either A modification of this construction is shown one or the other of the diverging tubes, the in Fig. 3, wherein the ends of the main and diverging tubes being connected together by switch tubes are made as a ball-and-socket 2 5 a segmental piece, and the end of the switchjoint at F, the rubber sleeve or gasket C sur- 75 tube having around it an air-tightcollar,which rounding the tubes and forming an air-tight bears against the surface of the segment. joint, as in the former case..

I claim as my inventioni. The combination, with the pneumatic tube A, of the pneumatic tubes A A2, the segment-piece C2, coilnecting the ends of the t-ubes A A2, the pneumatic switch consisting of a length ot' tube l5, pivotally connected to the tube A, and a ring and packing surrouinling the end of the tube l5 and adapted to bear against thc segment-piece G2, 'for forming an air-tight joint, substantially as set forth.

2. The combination, with the pneumatic tubes A A' A2, of the pneumatic switch consisting of a length ot tube B, the collar D and arms D', connected to the tube A, the collar E and the arms E', connected to the switchtubc l, the pivots conncctin said arms, the

rubber sleeve or gasket (l, surrounding the junction of the main and switch tubes A 13 and forming an ai r-tight joint, the segment C2, the collar c2 and its packing, and a helical spring that holds the same against the segment to form an air-tight joint, substantiallbv as set forth.

f). The combination, with the pneumatic tubes A A A2, ot' the pneumatic switch consisting of alength of tube 15, the meeting ends of the tubes A and B being curved and the one adapted to set within the other, the rub ber sleeve or gasket C, surrounding and connecting the tubes A and B and forming an air-tight joint, the segment C2, the ring c2 and its packing, and a helical spring adapted to press the ring and its packing against the segment to 'forni an air-tight joint, substantially as set forth.
